Question

Find the volume of cylinder having radius 2cm and height 2.5

Answer 1

$\huge \fbox \red{Answer}$

Given:

radius,r = 2cm

height,h = 2.5cm

To Find:

Volume of cylinder

Solution:

We know that,

Volume of cylinder = πr²h

$= \frac{22}{7} \times {(2)}^{2} \times 2.5$

$= \frac{22}{7} \times 4 \times 2.5$

$= \frac{22}{7} \times 10$

$= \frac{220}{7}$

= 31.42cm²

Answer 2

Answer:

220/7 (or) 31.4285714

Step-by-step explanation:

volume of cylinder :

$\pi \times {r}^{2} \times h$

22/7 × 2² × 2.5

22/7 × 4 × 2.5

22/7 × 10

220/7 (or) 31.4285714
